DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a chain guide for energy conductors for guiding energy conductors, in particular cables or hoses, from a fixed connection to a mobile load, or to two chain side plates which are spaced apart and parallel to one another. It has a plurality of chain elements consisting of cross members connecting these chain side plates to each other, and the mutual oscillating angle of these chain elements is defined by the stopper insert.
The present invention relates to a chain guide for an energy conductor.

[0002]

2. Description of the Related Art Such a chain guide for an energy conductor is known. For example, German Patent No. 3928
The chain guide device for energy conductors known from DE-A-238 238 has a plurality of chain elements consisting of two chain side plates arranged in parallel at a distance from each other and a cross member connecting these chain side plates to one another. The mutual swing angle of these chain elements is defined by the stopper insertion piece. The stop inserts are connected to one another via connecting pieces which are definitely routed to corresponding recesses in the chain side plate. The stopper insert also has a round head, which wraps around a round hole in the chain side plate. In this known chain guide for energy conductors, the mutual swing angle of the adjacent chain elements is defined by a stop cam which fits into the curved recess of the adjacent chain side plate. The stop cams or recesses formed in the chain side plates define a specific maximum swing angle, from which a specific radius of curvature of the energy conductor chain guide is obtained. In order to reduce the swing angle or increase the radius of curvature, the stopper insertion piece can be inserted into the recess. The stopper insertion piece forms a ring together with the connecting piece connecting them.

[0003] This known chain guide for energy conductors has proven itself for guiding energy conductors from fixed connections to movable loads.

[0004]

Starting from this prior art, the problem underlying the present invention is that the radius of curvature can easily be adapted to various use cases by turning or replacing the stop insert. It is to provide a chain guide for energy conductors.

[0005]

In order to solve this problem, in the chain guide device for an energy conductor according to the present invention, the stopper insertion piece is formed in a disk shape, and the two stop members are adjacent to each other in the length direction of the chain. It has two slits and recesses each diametrically opposed with respect to the mutual swing axis of the chain element, and these recesses determine the mutual swing angle of two adjacent chain elements in the longitudinal direction of the chain. The recess is formed in the shape of an arc extending in the circumferential direction, and of the two stop surfaces that partition the recess in the circumferential direction, the stop surface closer to the slit in the circumferential direction forms a specific angle with respect to the slit. Thus, a recess is provided in the stopper insertion piece, and a stopper cam is provided in each of the opposing recesses of the chain side plate of the chain element adjacent in the length direction of the chain, and the stopper cam is provided in the recess and the slit, respectively. Circumferentially Intrudes manner and so as not to give motion may come.

[0006]

The chain guide device for an energy conductor constructed according to the present invention has a simple construction of two stopper insertion pieces.
It has the advantage that it can be inserted into the recesses of two adjacent chain side plates. In this case, the stopper cam in the recess of one chain side plate fits into the slit of the stopper insertion piece, and holds the stopper insertion piece so as not to rotate in the recess of this chain side plate. Since the stop cam in the recess of the other chain side plate is guided in the recess formed in the arc shape in the stop insertion piece, the size of this recess in the stop insertion piece is two adjacent chain elements. Determine the mutual swing angle. Since the stopper inserts having arc-shaped recesses of different sizes can be temporarily used on the chain side, the swing angle can be adjusted to various use cases of the chain guide device for the energy conductor.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In an actual construction, a stop cam provided in a recess of a chain side plate belonging to one chain element of two chain elements adjacent to each other in the length direction of the chain faces in the length direction of the chain side plate.
The stop cam provided in the recess of the chain side plate belonging to the other chain element is provided at a specific angle with respect to the length direction of the chain side plate. This configuration facilitates the assembly, especially the insertion of the stopper insertion piece. The angle is preferably 90 °, so that the maximum mutual swing angle of the adjacent chain side plates is possible on both sides with respect to the length of the chain guide for the energy conductor.

[0008] The stopper insert has two slits provided diametrically opposed to each other and two recesses provided diametrically opposed to each other to determine the mutual swing angle of two adjacent chain elements. By virtue of having it, good guidance of the stop cam in the recess formed in an arc shape is achieved. Furthermore, in this configuration, it is advantageous if the stop insert is held against the chain side plate by two stop cams which fit into the slit. A stop insert is inserted into the recess of the chain side plate by turning through 180 ° around at least one of the two orthogonal axes, whereby the mutual swing angle of two adjacent chain elements can be defined in one direction or the other. It is.

The arc-shaped recess of the stopper insertion piece has two stopper surfaces, and the angle between the slit and the stopper closer to the slit in the circumferential direction is 90 °, whereby the chain element extends linearly. By being able to transition from the state to the curved state, the swing angle is reliably defined. For example, if the arc-shaped recess extends clockwise from the stop surface provided at 90 ° to the slit,
The two adjacent chain elements can be swung clockwise by an angle determined by the arc-shaped recess from a state of extending linearly. On the other hand, the arc-shaped recess has 90
数学 If the chain element extends in a mathematically positive direction from the offset stop surface, the two adjacent chain elements can swing counterclockwise from the state of extending linearly. With this simple configuration of the stop insert, the swing angle can be changed by rotating the stop insert 180 ° about the X or Y axis.

According to the invention, in order to be able to determine the swing direction of the energy conductor chain guide without troublesome disassembly of the chain side plate, the chain side plate is provided with an opening, The marker on the stop insertion piece can be confirmed through. Indicia can be provided on the stop insert, for example in the form of letters and numbers. The letters indicate the swing direction, and the numbers indicate the magnitude of the swing angle.

Finally, the stopper insertion piece has a center hole, and an appropriate tenon provided in the recess of the chain side plate fits into this hole.
Chain side plates of adjacent chain elements are connected to each other by connecting elements provided on the tenon. With this configuration, the energy conductor chain guide device can be easily assembled. In addition, the center hole in the stopper and the tenon of the chain side plate which fits into this hole ensure the correct positioning of the stopper in the recess of two adjacent chain side plates. This makes it possible to mechanically assemble the chain guide for the energy conductor.

Sliding pieces 19 are detachably attached to the upper and lower long sides of the chain side plates 2 and 3, and the upper side of the energy conductor chain guide device extending horizontally in a U-shape corresponds to the lower side. , These sliding pieces 19 slide on each other. So as to span the distance between the chain side plates 2, 2a adjacent in the length direction.
The length of the sliding piece 19 is determined. The sliding piece 19 is directly attached to the lower long side of the chain side plates 2 and 3, but is indirectly attached to the upper long side, that is, to the holding piece 9 of the rotary joint 7.

Each sliding piece 19 is formed in a plate shape, and has chamfered portions 20 provided at both ends in the longitudinal direction on the surface remote from the long sides of the chain side plates 2 and 3. The sliding piece 19 has four restraining elements 21 on the surface closer to the long sides of the chain side plates 2, 3, and can be fitted into a recess 22 in the chain side plates 2, 3 or the holding piece 9.

The mutual swing angle between the adjacent chain elements 2 and 2a is

Reference numerals 4 are provided in the circular recesses 26 of the chain side plate 2 and are arranged in the length direction of the chain side plate. The stop cam 23 at one end of the chain side plate 2a is provided in the circular recess 27 so as to be shifted by 90 ° with respect to the stop cam 24 at the other end of the same chain side plate 2a. As a result, the line connecting the two stop cams 23 is at right angles to the axis of the chain element 2a, and the other two stop cams 24 are on the axis of the chain side plate 2a. The chain side plate 2 has a rim 28 surrounding the recess 26, the outer diameter of which is smaller than the inner diameter of the recess 27, such that the rim 28 fits into the recess 27.

The chain side plates 2, 2a of adjacent chain elements are connected to one another by a coupling element 34, with the stopper inserts 25 being located in the recesses 26 and 27 of the chain side plates 2, 2a and extending in the radial direction of the recess 26. The slit 29 fits around the stop cam 24 having the slit 35. Thereby, the stopper insertion piece 25 or the chain side plate 2 is held so as not to turn into the recess 26. In this case, the stopper cam 23 located in the recess 27 of the chain side plate 2a is guided into the recess 30 which is opposed on the diameter of the stopper insertion piece 25. The mutual swing angle between the chain element 1 and the adjacent chain element indicated only by the chain side plate 2a is defined by the stop surfaces 31a and 31b. By arranging the stopper surface 31a at right angles to the slit 29 and forming the recesses 30 at a predetermined arc angle, the adjacent chain elements are changed from the linearly extended state to the arc angles of the recess 30. Only a corresponding angle can be swung in one direction. To change the mutual swinging direction of the chain elements, it is only necessary to turn the stopper insert 25 by 180 ° around one of its axes X or Y and insert it into the recesses 26, 27.
